b'C hoosing TheC orreCTB lAde3 BLADE WIDTH 4 PITCHlade the hoosingUse the blade width recommended by the machine manufacturer,Pitch is the number of teeth per inch/25mm. Cutting thinner sections except for contour cutting in vertical machines when you should userequires a finer pitch (more teeth per inch/25mm). Thick sections the chart below. require coarser pitches (fewer teeth per inch/25mm). B CThe charts are good guidelines. Because the cross section limits in the 1/2" chart are broad and overlap, choose a coarser pitch if the speed of cut (13mm)is most important. 3/8"(10mm) 1/4" Section to be Cut (in) Constant Pitch (TPI) Variable PitchBlade (6mm) 3/16"Width(5mm)1/8" 5/32" to 3/8" 32 or 24 14-18(3mm)1/4" to 1/2" 18 or 14 10-141/2" to 3/4" 14 or 10 8-12Radius 3/4" to 1" 10 or 8 6-101/8" 1" to 1-1/2" 8 or 6 5-8(3mm)1-1/2" to 3-1/2" 6 or 4 4-63-1/2" to 7" 4 or 3 3-45/16" 7" to 10" 3 2-3(8mm)10" to 16"1/4-214" to 20" 1/3 1-25/8" 16" to 32" 1/3 1-1/2(16mm)Over 30" 1 .8-1/3/.9-1/11-1/2"(38mm) 2-5/8"(67mm) For cutting tubes and profiles, use the horizontal line to find the outside diameter (tube) or the largest section (profile). Find the thickness (tube/profile) using the vertical column. With that information, cross them to find the recommended pitch.
